Scrap baling press truck

ABSTRACT

This provides a scrap-baling press truck having two press plates which are mounted on shafts arranged in parallel to the axles of the truck. The press plates fold over a pressing trough in which the scrap material is placed. A further feature of the invention provides an extension platform adjacent the base of the pressing trough. The extension platform can be hydraulically operated by a lever arm system on the lower portion of the truck platform. The scrap-baling press truck is especially adapted for baling scrap automobiles.

INVENTOR. MARTIN SCLIOELLHORN GEORG SCH FFLER Attorney i 1 SCRAP BALINGPRESS TRUCK This invention relates to ascrap-baling press truck forbaling large pieces of scrap material such as automobiles;

More specifically, this invention relates to a scrap baling apparatus,wherein the truck has the dimension and weight of a conventional truck,so as to meet legally acceptable road traffic requirements. f

All equipment known in the prior art which may be used for the purposesset forth in this invention are of such dimensions that they can only betransported on special vehicles. These known vehicles require a speciallicense for public traffic. In addition, such equipment is veryexpensive and difficult to 'handle in traffic.

Accordingly, this invention provides a scrap-baling press truck havingapressing trough which is located across the chassis platform of thetruck. The openfside of the pressing trough is so dimensioned thatlargepieces of scrap material may be gradually fed into thepressinglequipment. The scrap baling press truck is also capable ofpressing individual sec tions of large pieces of'scrap material'such asautomobiles. This capability requires relatively small pressing forcesso that a small dimensioned pressing trough is completely adequate. Inaddition, lighter duty press plates and hydraulic operation means areadequate for'the apparatus.

This invention also provides a scrap-balingpress'truck having foldingworking platforms arranged at. either side of the pressing trough. Thesefolding platforms can fold up during transit and include prop wheelattachments which support them once they are unfolded, Theplatforms intheir folded position form a pathway which includesthe pressing troughand may be tilted upward, or downward during the step-bystep travel ofthe scrapped bale. This enables large pieces of scrap material to be fedinto the pressing trough from the beginning to the end of thebalingprocess.

In an improved embodiment, a-lever arm is mounted on the lower portionof the truck platform for tilting the working platforms upward ordownward. A pistonrod of a hydraulic cylinder, which is supported by thechassis, is pivotably connected with the lever arm at the pivot point oftheplatforms. Connecting rods are provided to connect the pivot point ofthe platforms providing an auxiliary scrap-baling receiving means. Thelever arm and the connecting rod, permit a 90 angular tilting of theplatforms. The, scrappedbale, which first is pressed in itscenterportion, and which is about one-third of its total length, canthen be reciprocated on and along the trough on the bottomof the truckto subsequently press its front and rear portions. J-

The actuating pistons for the press" plates are mounted below thepressing trough, the press-plates being mounted parallel with respect tothe wheel axis of the truck. This necessarily provides a low'structurefor providing a compactness to the vehicle during transit. A loadingcrane is further provided behind the cab of the truck which has anunrestricted movement during loading. This capability of unrestrictedmovement is due to the structural characteristics of the baling pressequipment into which the large pieces of scrap material are beingplaced. Since the two auxiliary platform means have an additionalfunction, namely, to serve as feeder means for the piece to be pressed,the loading crane with its associated press means are thus relieved ofthe load, and the pressing operation can be accelerated. The auxiliaryreceiving means for the scrap baling reduces the pressing timeconsiderably, so as to considerably increase the output. The particulararrangement of the pressing equipment enables the structure of theloading crane to have a considerably shorter length than any of theknown prior art structures now available.

It is therefore an object according to' the present invention to providea scrap-baling press apparatus which can be mounted on a truck andcapable of pressing large scrap materials such as automobiles. I

It is another object according to the present invention to provide ascrap-baling press truck which is capable of handling large scrapmaterials under normal road conditions and regulations.

It is still a further object according to the invention to provide ascrap-baling press truck which is simple in design, effcient, andreliable in operation.

Other objects and features of the present invention will become apparentfrom the following detailed description considered in connection withthe accompanying drawings which disclose the embodiments of theinvention. It is to be understood, however, that the drawings aredesigned for the purpose of illustration only, and not as a definitionof the limits of the invention.

In the drawings, wherein similar reference characters denote similarelements throughout the several views:

FIG. 1 is a side elevational view of a truck incorporating the inventionof this disclosure;

FIG. 2 is a rear view of the truck incorporating the invention of thisdisclosure, shown in operating position; and

FIGS. 3 and 4 are scaled down views of FIG. 2, showing the differentpositions of the piece to be pressed during the operation of the device.

Referring to FIGS. l-4, there is shown a truck including a chassis lmounted on wheels 2 and carrying a drivers cab 3. An open, U-shapedpressing trough 4 is disposed across the truck platform. A set of pressplates 6 are mounted on shafts 5 and will fold over pressing trough 4 asshown by the broken lines of FIG. I. The axes 5 of plates 6 are mountedgenerally parallel to the axes of truck wheels 2. Pressing plates 6 arefitted with bell crank-type levers 7. Bell cranktype levers 7 areconnected to piston rods 8 whichare mounted in hydraulic cylinders 10.This forms a plate-operating mechanism. This mechanism moves thepressing plate in and out of a scrap pressing position. Piston rods 8and hydraulic cylinders 10 are mounted below pressing trough 4 andpivotably anchored by mounting means 9. i

Platforms 13 are shown in their folded out position and are flush withplatform 11 on the bottom of trough 4. Below platform 11 on each end ispivotably mounted levers 25 on axes 24. Piston rods 20, housed inhydraulic cylinders 23 are pivotably connected to levers 25 at axes 26.Cylinders 23 are pivotably coupled to chassis l by axes 22. Connectingrods 29 are connected at one end to lever arms 25 at pivot points 27.The other end of rods 29 is pivotably connected to platforms 13 by axes28. Rods 29 serve to enlarge the pivot radius of pivot point 12 ofplatfon'ns l3. Pivotpoints 12, 24, 27, and 28 for a quadrangle withtrough 4 serve as a frame with platforms l3, levers 25, and rods 29.This quadrangular joint makes it possible to maintain platforms 13 in aflush position with the bottom of trough 4. The object to be pressed, asshown in broken line, is put on the trough by grippers 17 of loadingcrane 16. The object is then pressed along its center portion a. Afterpress plates 6 are opened, the object is displaced by pivoting one ofplatforms l3 upwardly, as shown in FIG. 3, to permit the rear portion bto be pressed. After press plates 6 are opened, and the pivoted platformis lowered, the opposite platform 13 is raised, as shown in FIG. 4 sothat the remaining portion 0 can be pressed. Platforms 13 thus serve asa feeder means for transporting the object to be pressed so thatportions b and c may be properly pressed into trough 4.

The practicability of such a truck for moving in transit is clearlyexemplified by the compactness of the superstructure. As an example, atruck that has been readied to move may have its full height reduced toabout 3.55 meters and its width reduced to about 2.38 meters and aloading platform height of about 1.52 meters.

While only a few embodiments of the present invention have been shownand described, it will be understood that many changes and modificationsmay be made thereunto without departing from the spirit and scope of theinvention.
